public final class FunctionMatchQuery extends Query
DoubleValues
value matching a predicate
This query works by a linear scan of the index, and is best used in
conjunction with other queries that can restrict the number of
documents visitedConstructor and Description |

works properly.
Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals
